ATTACHMENT FOR ROPES FOB HAULAGE AND LIKE PURPOSES.

Specification of Letters Patent.

Application filed April 18, 1914. Serial No. 832,974..

To all whom it may concern:

Be it known that we, FREDERICK RINoRosn, a subject of the King of Great Britain, residing in Bothwell, Lanarkshire, Scotland, and THOMAS STEVENSON, a subject of the King of Great Britain, residing in Hamilton, Lanarkshire, Scotland, have invented certain new and useful Improvements in Attachments for Ropes for Haulage and like Purposes, of which the following is a specification.

This invention relates to capelling and associated devices for winding and haulage and like systems of the'kind wherein the strands at one end of the haulage or winding rope engage a helically fluted core or mandrel of tapered formation and are maintained in engagement therewith by means of a correspondingly tapered hose or capel.

The invention consists in the features of construction hereinafter particularly described and pointed out in claims, whereby more positive engagement of the strands of the rope with the fluted mandrel or core is insured and the capel or hose is maintained securely in position against accidental displacement in relation to the mandrel and the interposed strands.

In the accompanying drawings Figure 1 is a section showing a general arrangement of devices embodying the invention, the rope being omitted for the sake of clearness; Fig. 2 is a side elevation showing a modified construction of mandrel.

Referring to Figs. 1 and 2 of the drawings, a helically fluted or grooved mandrel 1 of tapered formation is employed, the flutes or grooves 2 in said mandrel being serrated or roughened and adapted to be entered partially by the strands of the rope, the strands being engaged by a hollow tapered capel or hose 3 which may be split lengthwise at one side thereof, or may be made up of two or more separable parts divided lengthwise of the hose, the strands of the rope being clamped between the mandrel 1 and the hose 3, preferably by means of internally tapered collars 4 in positive engagement, as heretofore, with the hose. As shown, the collars 4 are engaged externally by means of a sleeve 5 which is secured to the hose, as at 8, by means of studs or the like so as to prevent slackening of said collars 4: and consequently slackening of the hose 3 in relation to the strands of the rope and the mandrel l.

The mandrel 1 is formed with annular neck portions 9 which interrupt the helical flutings 2 and are of greater depth then said flutings, the strands of the rope being secured at the neck portions by means of cord, wire or the like, so that on attachment of the hose 3, the parts of the strands extending across the neck portions are constrained to enter therein, the strands being thus bound positively to the mandrel 1.

The mandrel l is formed at one end with a reduced extension 10 so as to afford a core for the free ends of the strands extending beyond the mandrel proper. At the opposite end of the mandrel there is formed a recess 1 for the reception of the free end of the central core portion of the rope, the said core portion being preferably wrapped with core or the like at a point exteriorly of the end 1 of the mandrel so as to insure that the strands of the rope will not bear excessively on the end 1*.

In addition to, or in substitution for, the reduced neck portions 9, the mandrel 1 may be formed with a helical groove 11, Fig. 2, interrupting the flutings for the strands and of greater depth than the flutings, cord, wire or the like being passed over the strands and led along the path of the groove 11, so that on attachment of the capel or hose the parts of the strands engaged by the cord, wire or the like are constrained to enter the groove 11, thereby binding the strands positively to the mandrel 1.
